Eyes on the Verge: A Night-Time Country Road Decision
You are driving a car at 85 km/h on an unlit rural road with a 90 km/h limit, on dipped beam, at about 23:00. The road is a gentle left-hand bend, patched with damp leaf litter. On the grass verge about 55 m ahead, in your headlights, you catch two small points of reflected light at roughly knee height, close together, that appear and disappear as the animal moves. A car has been following you for 3 km at about 15 m, and its near-side headlight is aimed high, filling your mirrors. An oncoming car is 150 m away and its main beam is still on. Your windscreen has a light film of grime on the outside, which smears the glare. A roadside marker post on your near side is 20 m ahead. You cannot see a safe place to stop for the next 400 m, and the verge drops into a ditch.
1. What do the reflections tell you, and what speed should you be doing now? Show your reasoning with the numbers given.

The paired reflections at knee height are characteristic of an animal's eyes catching the beam, and the way they appear and disappear means it is moving. Treat it as an animal that may step into the road without warning.
At 85 km/h you cover about 23.6 m every second. Thinking distance alone is roughly 21 m at a one-second reaction, and on damp leaf litter braking will add far more, easily 60 m or more from this speed. A hazard 55 m ahead is therefore already inside your stopping distance. Because the bend, the ditch and the close follower all argue against a sudden maximum-effort stop, the answer is to ease off now, cover the brake, and bring speed down to about 60 km/h so the verge is outside your stopping distance. Pick out a field gate or a gap in the verge as an escape route before you need it.
2. How do you handle the oncoming main beam and the tailgater at the same time?

Dip your own beam as soon as the oncoming car is close enough for your main beam to dazzle it, and look towards the nearside verge and the white edge line rather than into the lights. Your eyes adapt to the darker side of the road, and you keep your lane position. Do not retaliate with main beam or fog lights.
The follower at 15 m is the more dangerous problem: at 85 km/h that is well under a second's gap. Any braking must therefore be early and progressive, with a light first touch so the brake lights come on before the real deceleration. If the gap stays that close, ease off gently until the follower either drops back or commits to overtaking, and keep a longer gap to the hazard ahead so you never need an emergency stop.
3. If the animal does step out, what do you do, and what should happen immediately afterwards?
Read the worked answer
Brake firmly and progressively in a straight line with the steering wheel held still. Swerving at 85 km/h on a damp bend risks loss of control, a rollover, or a head-on with the car 150 m away, and an impact at reduced speed does far less harm than one at 85 km/h. Scrub speed even if a collision becomes unavoidable.
After impact, avoid stopping in the running lane. Indicate left, get as far onto the verge as the ditch allows, switch on hazard lights, and keep passengers behind a barrier rather than standing in the road. Report the collision if there is injury or significant damage, and do not approach an injured animal: a deer or badger with a broken leg can still kick hard.
